Nortel Teams With Leading Universities to Drive 4G Mobile Broadband

Nortel* [NYSE/TSX: NT] is teaming up with leading universities across the globe to develop new innovations that will help meet the growing demand for 4G mobile broadband applications like video, mobile TV and other multimedia services.

Nortel’s collaborative research with universities supports the new era of communications that is characterized by Hyperconnectivity, where everything that can be connected will be connected - encompassing person-to-person communication, person-to-machine and machine-to-machine.
To increase its competitive advantage and foster new 4G mobile broadband technologies, Nortel has expanded its existing long-standing research partnerships with leading universities like the University of Waterloo in Canada, The University of Texas at Austin in the U.S., and National Taiwan University (NTU) in Taiwan. Nortel has also formed new partnerships with Mera Networks in Russia and Technische Universitaet Ilmenau in Germany. Nortel’s investigations with these universities are designed to improve spectral efficiency, and decrease time to market for Nortel’s 4G mobile broadband solutions, which include Mobile WiMAX (IEEE 802.16e), and the Long Term Evolution (LTE) and Ultra Mobile Broadband (UMB) cellular standards.

“Through these university partnerships Nortel is sharing knowledge and expertise critical to identifying new disruptive technologies that help improve spectrum efficiencies and cost advantages that our service provider customers need,” said John Hoadley, leader, 4G Business and Ecosystem Development, Carrier Networks, Nortel. “Nortel is also laying the foundation for a future hyperconnected communication experience, where the number of devices and applications connected to the network will be greater than the number of people using the network.”

Nortel is expanding its existing relationship with the University of Waterloo which was announced in 2006 with Natural Sciences and Engineering Research Council of Canada (NSERC). Nortel is working closely with the Coding and Signal Transmission (CST) group of the University of Waterloo to increase the capacity of the future wireless networks through advanced multi-user transmission techniques. As part of its expanded partnership, Nortel is utilizing Waterloo’s on-campus research facilities to allow students and faculty to test and develop next-generation wireless technologies.

As an affiliate sponsor of The University of Texas at Austin’s Wireless Networking and Communications Group (WNCG), Nortel has been working with the university on the development of advanced 4G mobile broadband technologies, including MIMO-OFDM. MIMO and related advanced antenna technologies will help improve the spectral efficiency, network coverage and capacity of cellular base stations. This empowers service providers to deliver higher speed data applications including mobile video, gaming and other high-speed data transfers. Nortel and UT also have plans to work on advanced multi-user MIMO technologies and relay links to extend the coverage of cellular base stations. The goal is to enable a "true broadband" 4G experience everywhere by blanketing an area with small, relay access nodes, rather than costly base stations, to ensure high-speed, high-bandwidth capabilities.

Nortel announced collaboration with the Graduate Institute of Business Administration and the Electrical Engineering department of NTU on a WiMAX broadband service trial in 2006. The Nortel team is currently working with researchers at NTU on WiMAX proof of concept activities and interoperability testing geared at ensuring an end-to-end ecosystem is in place to support the widespread adoption of WiMAX. The work done with NTU will help to deliver enhanced capabilities over 4G WiMAX such as multimedia video conferencing with voice, video and IM, and location-based applications.

Nortel is also working with Mera Networks, the largest Russian Telecom R&D services provider and Technische Universitaet Ilmenau in Germany to develop advanced combinations of spatial processing and MIMO technologies. These advanced wireless radio techniques will improve network performance and increase capacity by re-using spectrum resources by as much as 4x over conventional systems. This will help improve the end user mobile broadband experience and allow carriers to deliver more high-speed data, including video and other multimedia services, more efficiently.

Nortel invests in approximately 50 technology innovation initiatives with more than 20 major universities and research consortia around the world to help fuel a new era of communications where all things and information are connected to an intelligent, pervasive mobile broadband network.
